The inverter is one of the key elements of every photovoltaic installation<\/a>. Although it is not as visible as the solar panels, its role is fundamental to the proper operation of the system. Let\u2019s explore how the photovoltaic inverter works and what functions it performs in the system.<\/p>\n\n\n\n

What is an inverter and how does it work?<\/h3>\n\n\n\n

An inverter is a device that converts the direct current (DC) generated by solar panels into alternating current (AC), which powers household appliances and devices. Most electrical devices in homes require alternating current with a voltage of 230\/400 V and a frequency of 50 Hz. Without the inverter, the electricity generated by the panels wouldn\u2019t be usable in everyday life.<\/p>\n\n\n\n

After converting the current, the inverter transfers energy to the power grid through a bidirectional meter. This allows surplus energy produced on sunny days to be sent back to the grid, while during periods of lower production, such as in winter, the user can draw energy previously supplied to the grid. This process, called net-metering, can lead to savings of up to 80% on energy bills.<\/p>\n\n\n\n
